GEORGE W. GANN ON, OF POUGHKEEPSIE, NEW YORK.

NAIL-SET.

SPECIFICATION forming part of Letters Patent N0.317,9'70, dated May 19,1885.

Application filed March 14, 1885.

To all whom it may concern.-

Be it known that I, GEORGE W. CANNON, a citizen of the United States,residing at Poughkeepsie, in the county of Dutchess and State of NewYork, have invented a new and use ful Nail-Set, of which the followingis a specification.

My invention relates to improvements in nail-sets.

Heretofore nail-sets have been made of steel with a smooth face, andthere was always danger of their slipping off from the head of the nailand bruising the wood when used.

The object of my invention is to remedy that difficulty; and I overcomeit entirely by placing upon the face of the nail-set a small conical orpyramidal projection which is hardened with the steel face, and whenstruck it enters the soft-iron head of the nail so as to prevent it fromslipping off the head of the nail. This projection is made by filing orturning away the other parts of the face of the nail-set be fore thesame is hardened or tempered. This projection is very small, muchsmaller than is shown in the drawings.

.Nailsets may be made of any required length and size of face, and minewill not slip off the head of the nail and does not wound or bruise thewood.

(Model) My nail-set is shown in the accompanying 3o drawings.

Figure 1 is a side view of my-nail-set. Fig. 2 is a full view of theface of the nail-set. Figs. 3, 4, and 5 are perspective views, showingthe different forms of the projection conical, as in Fig. 4, pyramidalwith qnandrangular or triangular base, as in Figs. 3 and 5-and theprojections may have any number of sided bases.

A shows the projection and B the body of 40 the nail-set.

b shows the face of the nail-set around the projection.

Having thus described my invention and its use and construction, what Iclaim, and desire to obtain Letters Patent for, is

A nail-set having on its flat face a sharp projection near the middle ofthe face, of less diameter than the face, either conical or pyramidal inshape, substantially as shown and 50 described.
